Specification of Letters Patent.

mimmo and Decemhr 5,1905. serie no. 290.431.

Be it known that I, HEINRICH LANGER, engineer, a citizen of the Empireof Austria, residing at Vienna, Austria, have im'cnted certain new anduseful Improvements in' Snperheaters for Locomotives andLocomotive-Boilers, of which thc following is a s eciication, referencebeing had therein to t 1e accompanying drawings.

My present invention relates to superheaters adapted to be located inthc tire-box of locomotives or locomotive-hoilers, and consists of anovel construction of a superheater in which the tubes forming the sanieare assembled and correlated in a novel inanner, said tubes in thepresent instance being located in a portion of the fre-box which isoutside of the jet flames.

My invention farther consists of other novel features of construction,all as will be fully hereinafter set forth.

In Figure 1 of the accompanying drawings. a boiler rovided with thesuperheater is illustratedj in longitudinal section. Fig. 2 is a sectionon the line A B of Fig. 1. Fie. 3 is a section on the line C l) of Fig.2. Figs. 4 and 5 show the superheatcr separately in longitudinal sectionand in vertical section on the line E I of Fig. 4.

On the cover of the lire-box a bundle of tubes a is arran ed next to thefire-door transversly of the oiler, Fig. 4. The cut-oil andregulatingvalves b anda of the superheater are arranged in prolongationsupon both sides of this latter. The superheater is rotected from thedirect action of the tire y providing beneath it a chainottc arch r, or

it may be directly covered with refractory material. The rei'nainder ofthe arrange ment is preferably such that the wet steam is taken at anappropriate partei the wetsteani chamber m and conducted to the superheater a, through a pipe j, inclined. relatively thereto. From thesuiierlicater a the steam passes through a second pipe g,

running parallel with the pipef, into a c 1ambcr n, separated from thewot-steam] chaniber. lt then passi-s, in the known islamici', throughthcV regulator to the slidcfvalve chest. Il' the supcrlicater is 'filledwith wa ter before the boiler-furnace is kindled, it 4likewise serves tohasten the generation of steam.

What l claim, and desire to secure by Letl ters Patent of the UnitedStates, isw- 1. In a device of the character described, a tire-box, aboiler, a superheater located in the rear of-the angle of said fire-boxand removed from the direct action of the llame, refractory materialintermediate said firebox and said superheater, and connections betweensaid superheater and said boiler.

2. In a device of the character described, a firebox, a boiler having aplurality of chambers, a supcrlieater located above said lirebox,refractory material between said tirebox and said su erheater, a conduitleading from said super eater to one of said boilerchambers, and aconduit leadinnr from isaid superheater to the other of saidcliarnbers.`

lire-box, a boiler having a plurality of chambers, a superheater locatedabove said fire box, refractory material between said firebox and saidsuperlieater, a conduit leading from one of said chambers to said. suerheater, a valve therefor, a conduit lea ing from the other of saidchambers, and a valve for the last-mentioned conduit.

4. In a device of the character described, a tire-box, a boiler having aplurality of charn- `bers, superlieater-tubes located above saidfire-box, refractory -niaterial between said tire-box and saidsuperheater-tubcs, a valvcd conduit leading from one of saidboiler-chainbers and communicating with said tubes, and a valved conduitleading from the other of with said superheater.

5. In a device of the character described, a tire-box, a boiler having aplurality of chambers. superheater-tubes located above said ltire-box.and transversely of said boiler, refractory material between saidlire-box and I said snperheater-tubes, 'a valved conduit leading rom oneof said boilenohambers and l communicating with said tubes, and a valvedl conduit leading from the other of said boilerchambers andYcommunicating with said superlieater.

3. In a device of the character described, a
